1-1. What is DVM?
The DVM(Digital Variable Multi) air conditioning system is operated by a variable-capacity compressor
and is accommodated by multiple evaporators (indoor units). It is touted as the next-generation modular
system in the world of high-efficiency air conditioning. lt has undoubtedly changed the face of cooling
associated with high-storied buildings. It provides a broad range of different applications for settings such
as offices, hotels and schools. With its easy installation and simple controlling system, the DVM will more
than meet the demands of the air conditioning market.

1-2. Features of DVM
(1) Customized air conditioner
1) Up to 16 indoor units can be connected to one outdoor unit.
2) Indoor units can be combined by various methods, according to each room’s use and shape.
3) There are several indoor units which can be applied; 1-way cassette type, 4-way cassette type,
Ceiling, Duct (Low silhouette, Built-in, High pressure), Wall-mounted and Floor standing type.
(2) Comparison of DVM with conventional air conditioners
1) DVM air conditioner
①
Variable capacity (Energy Saving)
②
Competitive price (Compared with the Inverter type)
③
Can be installed in houses / commercial buildings
④
Versatile combination of indoor units
⑤
Various remote controls
2) Conventional air conditioners
①
Fixed capacity
②
Unfavorable in case of installing more than 3 units / system

(3) Variable compressor
The world’s first PWM(Pulse Width Modulation) compressor controls the cooling & heating capacity
automatically, depending on the load.
1) Principle of the digital compressor
①
Composition
A solenoid valve is installed for compressor´s loading / unloading between the upper part of the fixed
scroll and the suction pipe.
②
Mechanism
a. When the solenoid valve is turned off, the fixed scroll is closed to the orbiting scroll (Loading),
b. When the solenoid valve is turned on, the fixed scroll is separated from the orbiting scroll (Unloading),
c. This process controls the On / Off turning of the valve, thus adjusting the capacity of the compressor.
d. The cooling capacity of the outdoor unit is controlled automatically, depending on the
number of operating indoor unit(s).
